Figure 2From: Group I introns and associated homing endonuclease genes reveals a clinal structure for Porphyra spiralis var. amplifolia (Bangiales, Rhodophyta) along the Eastern coast of South AmericaTranslation of homing endonuclease gene open reading frames of the five size polymorphisms. The His-Cys box motif is underlined and zinc binding sites and active sites found in I-PpoI endonuclease are indicated by line above amino acids. Stop codon is indicated by asterisk. End of sequence without stop codon is indicated by +. H – haplotype.Back to article page
